Definitions

  • the invention relates to a current collector holder for a carbon shoe, which bears against a contact wire, for electrically driven vehicles, which holder has two first webs, which grip the foot region of the shoe, and two second webs, which project away from the shoe and are arranged underneath it, a separate spring system being provided which presses the second webs relatively towards one another and hence presses the first webs against the foot region of the shoe.
  • the holder is connected to the current collector via side elements, so-called horns.
  • the spring system is formed by a plurality of spiral springs which act on the second webs at discrete points on the second webs, oriented transversely with respect to the longitudinal direction of the shoe.
  • This construction is relatively complicated and its mass is very high.
  • the forces do not act continuously over the entire length of the second webs, as a result of which stresses are caused in the carbon shoe.
  • the contact voltage drop between the carbon shoe and the holder is relatively high.
  • the invention is based on the object of constructing the holder mentioned initially in such a manner that it is simpler than that known and in such a manner that the spring forces act continuously over the entire length of the shoe.
  • This construction is achieved according to the invention in that a spring is provided as the spring system, which spring extends unchanged in the longitudinal direction of the shoe, bears against the second webs with longitudinal regions, and in this way transmits its spring force, which acts in the transverse direction of the shoe, to the second webs.
  • This construction is distinguished by simplicity. This has a favorable effect on production and allows the use of worn carbon shoes in a simple manner.
  • the spring acts continuously over the entire length of the second webs. This leads to it being possible to hold the carbon shoes with forces which remain constant in the longitudinal direction, in a manner which is simpler than in the known case, which, as a result of the specific brittleness of the carbon shoe, is better than retention of the same with forces which act differently in the longitudinal direction.
  • the electrical contact resistance from the carbon shoe to the holder is then constant and smaller over the entire shoe.
  • a development of the invention is for the spring to form an open figure in the transverse direction of the shoe, which figure is curved on one side, has two mutually opposite edges, grips the second webs and presses them against one another.
  • the spring is additionally provided with the radius of the holder.
  • the spring it is also possible for the spring to be provided with transverse slots which end shortly in front of the edges.
  • the spring may have holes into which hooks can be inserted, by means of which the springs can be pulled out of the shoe.
  • the spring is a leaf spring which is slightly curved in the transverse direction of the shoe, is arranged between the second webs and presses the latter apart.
  • the spring prefferably to form a closed figure in the transverse direction of the shoe, which figure is curved on one side, is arranged between the second webs and presses the latter apart.
  • the spring of this type can be hollow inside, but it can also be solid internally and be composed of strongly elastic material.
  • the spring wall could be constructed elastically, there being compressed gas, especially compressed air, in its interior in a controlled manner.
  • first webs be connected to one another via a wall which is arranged underneath the second webs.
  • the holder without a spring is then integral. If the first webs are not connected to a wall, then the holder without a spring comprises two halves.
  • the second webs which extend over the entire holder length is for said webs to be short pieces in the longitudinal direction, which short pieces are connected to the first webs on the right and left alternately and interlock.
  • the holder without a spring comprises two parts. If the first webs are connected to a wall underneath the second webs, then the holder is integral.
  • the second webs have laterally projecting shoulders at their free ends, behind which shoulders the spring engages.
  • the spring comprises a plurality of pieces which are adjacent to one another, with or without a space. This construction is particularly interesting if the shoe is bent transversely with respect to the contact wire.
  • a further construction of the invention is for a sensing element, which records the mechanical oscillations of the shoe, to be located on the holder.
  • This sensing element is connected to an indicating apparatus.
  • the indicating apparatus indicates a specific mechanical behavior of the sensing element and hence of the shoe. Defects of the said type lead to deviations from this indication.
  • first webs are connected to one another via a wall which is arranged underneath the second webs, then it is expedient to arrange the sensing element in the space above this wall.
  • FIG. 1 shows a section through a first embodiment of the invention, in accordance with the line I--I in FIG. 2,
  • FIG. 1a illustrates a variation of the embodiment of FIG. 1 in which the spring is in a closed configuration
  • FIG. 2 shows a view of the first embodiment from underneath, without a spring
  • FIG. 2A illustrates the embodiment of the invention shown by FIG. 2 in which the spring is formed from a plurality of adjacent pieces
  • FIG. 3 shows a section through a second embodiment corresponding to FIG. 1,
  • FIG. 4 shows a section through a third embodiment of the invention corresponding to FIG. 1,
  • FIG. 4A shows a section through the embodiment of the invention illustrated by FIG. 4, taken along directional lines X--X, illustrating a sensing element
  • FIG. 5 shows a perspective view of a spring
  • FIG. 6 shows a further embodiment before assembly
  • FIG. 7 after assembly
  • FIG. 8 and FIG. 8A illustrate, respectively, a spring having an upwardly projecting bulge illustrated in perspective, and a sectional view of a device in accordance with the present invention in which said spring having said upwardly projecting bulge is in an operative position in which the bulge presses a contact strip inserted between a carbon shoe and a holder against the carbon shoe.
  • FIGS. 1 and 2 designates a carbon shoe, 2 a holder for said carbon shoe, comprising the parts 2a and 2b, and 3 a leaf spring.
  • the holder has first webs 4 which grip a foot region 5 of the carbon shoe.
  • the holder has two webs 6 which have inwardly projecting shoulders 7 at their free ends. Said shoulders 7 are used as retention for the spring 3.
  • the latter is bent slightly in the transverse direction of the shoe and exerts a pressure on the webs 6 which leads to the webs 4 firmly gripping the foot region 5 of the carbon shoe 1. If the spring 3 is pulled out vertically with respect to the plane of the drawing in FIG. 1, then, inter alia, the two parts 2a and 2b are detached from one another.
  • FIG. 1a illustrates an embodiment similar to that of FIG. 1 in which the leaf spring 3 of FIG. 1 is replaced by a closed spring 3A illustrated in FIG. 1a.
  • FIG. 2A illustrates an embodiment of the invention similar to that shown in FIG. 2 except FIG. 2A illustrates that the spring element is formed from a plurality of separate, adjacent pieces 22, 24, 26 and 28.
  • FIG. 3 differs from the embodiment in FIGS. 1 and 2 essentially in that the carbon shoe 1 has an inwardly expanding section 10 in the central region, into which first webs 14 engage. Otherwise, this embodiment corresponds to the embodiment in FIGS. 1 and 2.
  • the holder 16 is integral. It has first webs 4 and second webs 6. Otherwise, a wall 17 is provided which connects the webs 4 to one another, runs underneath the webs 6 and forms a space in which the webs 6 and a spring 18 are located. Said spring 18 is bent transversely with respect to the longitudinal direction of the shoe and presses the second webs 6 against one another. In this way, the first webs 4 are also pressed against one another. To this extent, they hold the carbon shoe 1 firmly.
  • a sensing element 30 (shown in FIG. 4A) can be located in the space above the wall 17, which sensing element detects the mechanical behavior of the shoe (oscillations, shocks etc.). In this way, it is possible to test various aspects: during normal operation, the holder will execute a specific oscillation. A deviation from this oscillation occurs when, for example, the carbon shoe has defects such as cracks, delaminations or fractures. Defects in the overhead line and, to a certain extent, problems in the track bed, can also be proven.
  • FIG. 5 shows a bent spring 18 with opposite edges 19.
  • the spring is provided with transverse slots 20.
  • a hole 21 is located at the end of the spring 18.
  • a hook can be engaged in said hole 21 and the spring can then be pulled out.
  • Two dashed lines 22 indicate an alternative: the edges could be formed in such a manner for the purpose of pushing the spring on more easily.
  • FIGS. 6 and 7 show an embodiment before and after assembly.
  • the holder is composed of, for example, aluminum.
  • the parts namely the holder and the carbon shoe, can, naturally, also be bonded or soldered to one another.
  • a further embodiment of the invention is for the spring 22, apart from its central region, to form an open figure in the transverse direction of the shoe, which figure is curved on one side, has mutually opposite edges, grips the second webs and presses them against one another and, in its central region, for the spring to have an upwardly projecting bulge 25, which presses a contact strip 36, which is inserted between the carbon shoe 34 and the
